Amber light of death

[XSV]

Okay I have been into zipzaps off and on for the past here now. I recently went to my local radioshack and bought a bunch of clearance zipzaps. Then a couple of months later I am trying to play with them and had really never used them before. I come to find out that none of them work except for the lights and steering. So I take off the bodies and on one I put in an old ZZ motor and old ZZ motor clip. I try it out and charge it up run it in my hands and it works perfectly(without the body on) so I put it on the ground and it doesn't work. I repeat this with the same results. The third time I try it i just keep it running. It works fine that time. So I go back to my room and put on the Aston Martin Body and plug it in. Now when I charge it I will get the Amber light. So I try to shut off the ZZ and turn it back on, shut off the charger and turn it on again, and run through all the channels all this to no avail.I still get the Amber light. So I shut off the charger to type this and as I'm trying to take the body off (which is very hard and I fail) So for some reason i turned it back on and accidentally pressed the trigger and it works!! Why is my SE doing all these strange things?

Edit: Now after that use I try and charge it and I get he Amber light again. It seems to be charging it though.
